  abstract = {{T}he early {P}leistocene was driven by 41 kyr glacial cycles that have been rarely characterized in continental records, especially in {S}outh {A}merica. {M}ost of long-term records derive from marine records (e.g. sea surface temperatures ({SST})) and have been widely used to infer past climate dynamics but implications for the continent have rarely been evaluated. {W}e present an early {P}leistocene record ({COL}17c) from the {C}olonia basin in the {A}tlantic forest domain in southeastern {B}razil. {O}ur aim was to integrate past environmental dynamics and the drivers of change between ca. 1.5 to 1.3 {M}yr at the latitude of {C}olonia (23 degrees {S}; ca. 700 m a.s.l.). {W}e applied a multi-proxy approach including pollen, charcoal, {X}-{R}ay fluorescence scanning ({XRF}), biomarkers and diatoms. {W}e identified three glacial periods and four interglacials containing a continuous cool forest, mainly dominated by {A}raucaria. {T}he glacial periods were characterized by increases in organic matter input on the lake, semi-deciduous forest, and shore and herbaceous vegetation. {I}n contrast, the interglacials were marked by increases in evergreen forest and reduced organic matter input. {W}e attribute these alternating phases of vegetation and lake productivity to meridional temperature differences that regulated the input of moisture at the latitude of {C}olonia. {A}fter 1.430 {M}yr, glacial and interglacial periods showed a different dynamism with an increase in {A}raucaria forests and drops in relative temperature, concomitant with regional long-trend cooling observed in marine records. {T}he observed forest responses inferred from the {COL}17c record are in phase with regional climate features such as the development of the cold {P}acific tongue and the equatorward migration of subpolar fronts, highlighting the strong influence of the {S}outhern {H}emisphere at {C}olonia during the early {P}leistocene.},
